Glaucoma secondary to oth eye disord, right eye, stage unsp

This code signifies elevated intraocular pressure and optic nerve damage in the right eye, where the glaucoma is a direct consequence of another pre-existing ocular condition. This distinguishes it from primary open-angle glaucoma or glaucoma caused by trauma or inflammation. The specific stage of glaucoma progression is not documented or determined.

Apply this code when documentation clearly indicates glaucoma in the right eye resulting from an underlying eye disorder, such as retinal detachment, intraocular tumor, or severe myopia. The physician's notes should explicitly link the glaucoma to the secondary cause and specify the affected eye.

• Always code the underlying eye disorder first, as it is the primary cause of the glaucoma.
• Ensure the documentation specifies "right eye" and that the glaucoma is secondary to an other eye disorder, not trauma or inflammation.
• If the stage of glaucoma is known, use a more specific code from the H40.51 category (e.g., H40.51X1 for mild stage).
